WAGON-BOX. LOCK.

SPECIFICATION forming part of Letters Patent No. 355,459, dated January4, 1887.

Application filed October 25, 1886. Serial No. 217,128. (Nomodeh) To aZZwhom it may concern..-

Be it known that we, JOSEPH MARX and JosEPH H. MUELLER, both of CrossPlains, in the county of Dane and State of VVisconsin,have invented anew and Improved Vagon- Box Look, of which the following is aspecification, reference being bad to the annexed drawings, forming apart thereof, in which Figure 1. is an end View of a Wagon-box with ourimproved lock applied. Fig. 2 is a plan view of the lock detached fromthe wagonboX; and Fig.3 is a plan view of a portion of awagonboX,showing the lock in position for removal from the box.

Similar letters of reference indicate corresponding parts in all theviews.

The object of our invention is to provide a simple and efficientfastening or look for the end-gates of wagon-boxes, which may be quicklyapplied and readily removed.

Our invention consists in two T-headed rods pivoted tothe ends of theshorter arms of a T-lever, and a pawl connected with the longer arm ofthe T-lever, adapted to engage notches in one of the T-headed rods, allas hereinafter more fully described.

The rods A B are provided at their outer ends with T-sha'ped heads a,and are pivoted at their inner ends to the shorter arms I) b of theT-shaped three-armed lever G. The lever O is arranged to swingin a planeat right angles to the 'heads a, and to thelonger arm of the lever G ispivoted a pawl, 0, having at its free end an eye, (I, which surroundsthe rod A, and is adapted to engage a series of ratchetteeth, 6, formedon the edge of'therod.

In the cleatsf of the end-gate D, and in the sides of the wagon-box,areformed mortisesg, (shown in dotted linesin Fig. 1,) through which theheads a of the rods A B may be passed. The sides of the wagon-box areprovided with plates h, having apertures corresponding to the mortisesg, for receiving the pressure of the heads a.

through the mortise g, as shown in dotted lines in Fig. 3,'until thehead a of the rod A can be inserted in the mortises g of the oppositeside of the end-gate of the wagon-box, when the lock is slidin theopposite direction, bringing the heads a on opposite sides of the Thelever O is then turned down 1 into a vertical position, bringing theheads a at right angles to the mortises g. The leverO is then swungaround so as to draw the ends of the rods A B together, as shown indotted lines in Fig. 1, thus clamping the sides of the wagon-box firmlyagainst the ends of the end gate. The pawl c engages the ratchet-teeth eof the rod A'and holds the lever O in the position in which it isplaced. When it is desired to unfasten the end-gate, the pawl c isdisengaged from the ratchet-teeth e, and the rods A B are removedfromthe mortises by reversingthe operation just described.

The device which we have described in connection with theend-gates ofwagons mm appliedto the straining of saw-frames.

Having thus fully described our invention, we claim as new and desire tosecure by Letters Patent 1. The combination of therod A, provided withthe T-shaped head a and ratchet-teeth e, the rod B, provided with theT-shapedv head a, the T-shaped lever O, pivotally connected with therods A B, and the pawl c, pivoted to the lever O and adapted to engagethe ratchet-teeth e, substantially as described.

2. The combination, with the wagon-box and end-gate providedwithmortises g and plates h, of the rod A,provided with the head a andratchet-teeth e, the rod B,provided with the head a, the T-shaped leverG, pivotally connected with the rods A B, and the pawl c, pivoted to thelever O and adapted to engage the ratchet'teeth e, substantially asdescribed.
